They would survive and adapt easily, or at least that's what deviantART artist Kasami-Sensei's artwork suggests. He put several Disney characters into the Walking Dead universe, making all the appropriate changes. It's weird to see Anna from Frozen with an M4 carbine, but you can't survive otherwise.

Here are some highlights. My favorite is definitely the one with Hades with a flamethrower. Head over to the artist's page for a lot more.
